Integration Of Dd; Reading The Parameters; Continuous Record Of Values - YOKOGAWA digitalYEWFLO Series User Manual

Unless otherwise specified, the following settings
are in effect when shipped from the factory.
If no digitalYEWFLO is detected, check the
available address range. If the node address and
PD Tag are not specified when ordering, default
value is factory set. If two or more digitalYEWFLOs
are connected at a time with default value, only
one digitalYEWFLO will be detected from host as
digitalYEWFLOs have the same initial address.
Connect the digitalYEWFLOs one by one and set a
unique address for each.

Integration of DD

If the host supports DD (Device Description), the
DD of the digitalYEWFLO needs to be installed.
Check if host has the following directory under its
default DD directory.
594543 : the manufacturer number of
Yokogawa Electric Corporation
0009 : the device number of digitalYEWFLO
If this directory is not found, the DD for the
digitalYEWFLO has not yet been installed. Create
this directory and copy the DD files (0m0n.ffo and
0m0n.sym to be supplied separately where m and
n are numerals) to it. If you do not have the DD files
for the digitalYEWFLO, you can download them
from our web site.
Visit the following web site.
http://www.yokogawa.com/fld/
Once the DD is installed in the directory, the
name and attribute of all parameters of the
digitalYEWFLO are displayed.
Off-line configuration is possible using the
capabilities file.

capabilities:
• General type:
AI function blocks (three), DI function blocks
(two), AR function block (one), and IT
function block (one).
• With the option /LC1: A PID function block
Using the wrong CFF file may result in an
error when downloading the configured data
to the device. Also, use the right DD files that
accommodate the revision of the intended
device.
